Security & OS Feature Engineering Design and implement Windows security and enterprise capabilities that ship at scale across client and/or server. Build features across foundational areas such as hardware-backed security, cryptography, identity/authentication, and enterprise management experiences. Contribute to incident response, root-cause analysis, and continuous hardening efforts that improve Windows security posture over time. Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. Solid experience building and shipping production software in one or more systems languages (e.g., C/C++/C#) and debugging complex systems. Experience designing and developing features in large-scale, performance-sensitive systems, ideally with Windows / OS / systems depth. These requirements include but are not limited to the following specialized security screenings: Experience in one or more: platform security, cryptography, identity/authentication, secure boot/TPM, device security, enterprise policy/management, licensing/entitlement systems. Track record of driving engineering quality: testing strategy, telemetry, reliability, and operational excellence. Comfort partnering across geographies and influencing designs with stakeholders across engineering, security, and program leadership.
